Double Wall Plastic Storage
Tanks - Choice of Plasic Resins
We make an extended range of
double wall chemical storage tanks. Our tanks of
3,000 gallons and below can be made from High Density
Polyethyelene (HDPE), from Polypropylene and from
Polyvinylidene fluoride (PVDF). The best known brand
name for PVDF is Kynar. The two most common reasons for
choosing a particular resin other than polyethylene are
the need for a higher continuous use temperature and
compatibility with a particular chemical. You can check
chemical compatibility of the chemical you are
storing with our tank resins by
Polypropylene is the next most popular
selection. It is often chosen when a continuous use
temperature of up to 200 degrees F. is needed.
Polyprolylene is also compatible with some chemicals
that do not play well with Polyethylene.
molded Polypropylene is brittle so care must be taken to
keep it from impact.
fluoride)is a great resin since in certain applications it
has a continuous use temperature of nearly 300 degrees
F. PVDF has good chemical compatibility. The limiting
factor on PVDF for Double Wall Storage Tanks is that
PVDF is expensive. Consequently, PVDF is selected only
when the storage application requires the special
properties that PVDF brings.
